t-Butyl nitrite (4 ml) was added to a mixture of 5-chloro-2-methylaniline (4 g) and dimethyl disulphide (26.3 g) in chloroform. After the reaction started t-butyl nitrite (17.7 ml) and 5-chloro-2-methylaniline (16 g) were added simultaneously. The mixture was stirred at room temperature for 2 hours and left to stand overnight. The mixture was washed with water, aqueous hydrochloric acid (2M), water, dried (anhydrous magnesium sulphate) and filtered. The filtrate was evaporated to dryness to give 4-chloro-2-methylsulphenyltoluene (24.6 g) as a red oil, NMR (CDCl3): 2.2(s,3H), 2.4(s,3H), 6.85(s,2H), 7.0(s, 1H).
